  title: Efí (formerly Gerencianet) Payments Authorization Pix Webhooks API
  description: "Representative subset of Efí's public REST APIs for the Brazilian financial system. Efí (ex-Gerencianet) is a Brazilian payment institution and digital bank. This document groups operations across several distinct API hosts, each with its own base URL and authentication requirements:\n\n- Pix API - base https://pix.api.efipay.com.br (sandbox\n  https://pix-h.api.efipay.com.br). OAuth2 client-credentials (token at\n  POST /oauth/token) PLUS a mandatory mutual TLS (mTLS) client certificate\n  (.p12/.pem) on every request, as required by the Brazilian Central Bank.\n  Paths under /v2/*.\n\n\n- Cobranças (Charges) API - base https://cobrancas.api.efipay.com.br (sandbox\n  https://cobrancas-h.api.efipay.com.br). OAuth2 client-credentials over HTTP\n  Basic (token at POST /v1/authorize). No mTLS certificate required. Paths\n  under /v1/charge, /v1/charges, /v1/carnet.\n\n\n- Pix via Open Finance API - base https://openfinance.api.efipay.com.br\n  (sandbox https://openfinance-h.api.efipay.com.br). OAuth2 client-credentials\n  (token at POST /v1/oauth/token) PLUS a mandatory mTLS certificate.\n\n\nBecause OpenAPI 3.0 has a single security-scheme model, the mTLS requirement for the Pix and Open Finance hosts is described here in prose and cannot be fully expressed as a securityScheme; treat the mTLS client certificate as mandatory on those hosts in addition to the OAuth2 bearer token. Endpoints marked \"modeled\" in the repository review follow the Brazilian Central Bank Pix API v2 standard that Efí implements; the create/query charge, webhook, charge, and carnê operations were confirmed directly against Efí's public documentation."

This is an independent, third-party profile of Efí Pix Webhooks API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
